Sedaia [141]

Answer:

Taco supreme is 1230 calories

Pan pizza is 1310 calories

Step-by-step explanation:

Let's denote taco supreme as T and pan pizza az P. We have:

T+2*P = 3850 and 2*T + P = 3770

If we add the equations we get 3*T+3*P = 7620

3*(T+P) = 7620

T+P = 2540 => we can use T=2540-P

Back to one of the first equations we get 2540-P+2*P=3850

P=3850-2540= 1310

=>T= 2540-1310= 1230
